Premium, Sweden, iPhone 12, MBA 2020, Sonos speakers (mostly use the Spotify connect of convenience, even though sonos own app seem more reliable).
I recently (maybe some month ago) started experiencing random pausing in Spotify when playing music. It's mainly (and possibly only) an issues on iPhone. It might average on once or twice every hour. I use AirPods Pro. And it does seem to happen both on wifi and cellular. I haven't succeeded to identify any correlation between different combination of factors the issue occur.
I've tried to log out of every device from Spotify webpage and change password, just to be sure no one else is using my account. But that didn't make any difference.
